Barley SXM Genotypes Information
A population of 150 doubled haploid lines was developed from the Steptoe x Morex cross by the Hordeum bulbosum method. The parents were selected for their diversity of agronomic traits, Steptoe is high yielding, broadly adapted six-rowed feed-type barley. Morex is midwestern also six-rowed cultivar that has been for long time considered as the American malting industry standard. Please cite the following publication when using the Steptoe x Morex (SxM) data sets: Genotyping by using Illumina GoldenGate BeadArrays and barley pilot OPA1 (1536 SNPs, Rostoks et al 2006) identified 424 good quality SNPs. They were integrated into the RFLP map that contained 632 markers (1202 cM) by using Map Manager QTX (ver 0.27). Final, 1082 cM map, consisting of 505 loci including 227 SNP loci was generated by removing co-segregating markers (leaving a single marker per locus) and correcting the spurious recombinations.
